Well, you could return 1 for true and 0 for false:

>>> print 1==1, type(1==1), 1==0, type(1==0)
1 <type 'int'> 0 <type 'int'>

Python does not have a distinct boolean type, if that's what you're
asking. Empty lists, empty strings, 0, 0L and 0.0 are false,
everything else is true (except for instances of classes that have
__nozero__ methods, which get to decide for themselves).
